To all whom. it may concern:

Be it knownthat we, VILLIAV FREE, a citizen of the United States, residing at Chicage, in the countv of (oolr and State of Illinois, and Josnrn B. Axoovn, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a s iecilic-ation.

The invention rc lates in part to means for flipping the shuttle out of its carrier and in part to the combination with said flipping means of means for preventing the slide orcovcr of the shuttle race from rattling or moving at random. Preferably a single device is used for accomplishing these two 0bjeets, said device being of such construction that when the slide is in place it bears against the under side, thereof with sufficient force to produce the amount of friction necessary to prevent it from rattling or moving at random but not sul'licien't 'to prevent its eas manipulation, and, when the slide is remover either wholly or sufficiently to give access to said device, it may be so manipulated as to throw or flip the shuttle out of the carrier.

\Ve desire to have it understood, however that the invention is not limited to the dual function of this device and if desired the locking function may be dispensed with.

To these ends the invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawing, which is made a part of this specification, and in which;

Figure 1 is a )lnn view of a portion of a sewing machine lead with our im roved device applied, the front slide of t to shuttle race bein omitted; Figs. 2 and 3 are vertical sections thereof on the lines.22, and 33, Fig. 1, respectively.

A represents the base-plate of the head of a sewing machine, B, the shuttle, (shown in outline), C, the shuttle-carrier, and D the shuttle-carrier arm, ivotally supported by the base-plate at All of these parts may be of any desired construction, so long as they are suitable for the carrying out of the invention. The shuttle race, F, is concentric with the )ivotal center, E, of the arm, D, and at tie end of the shuttle race the base-plate has a cove or recess, G, into which the point of the shuttle extends, when at the limit of its forward movement. The base-plate has the customary milled shoulders, II, and undercut groove-s. I, for receiving the beveled edges of the slide, J, and between these shoulders the base-plate has a groove, K, in which the device. L, embodying our invention is secured, This'device. is preferably made of a single iece of spring metal stamped to shape. t comprises a flat portion, I, which tits upon the ottom of the groovc, K, and is perforated for the iazc a c of the retaining screw, M, an upward y and rearwa rdly cxtendilg portion, l, which acts as a 5 )ring and is slotted to redu'ce its rigiditv, a read or button, I", at the extremity of the spring and a tail piece, I, of inverted V-shape. The head or button is preferably rough and is located o er the oint of the shuttle when the latter is at the limit of its forward nmvement, so that by pressing downward on the head or button it will strike the point of the shuttle and flip" it out of the carrier. This device S sim ale and effective and avoids the necessity or prying the shuttle out of the carrier by means of a pair of scissors or other im )lement- \Ve desire to have it understood, however, that in its-broadest aspect the invention is not limited to a roughened head, or, in fact, to a head of any description. because a straight spring dis )osed as ucscribed would give good results. \it we prefer to use an enlarged head, as it gives a broader bearing" surface for the finger and we prefer to rougmcn it as the pressure is being applied.

Another function of device is to prevent the. random movement of the siide, J, and to this end the head I" of the spring I, normally occupies a lane somewhat above the plane of the shou itiers, H, so that when the slide is in place the spring bears against the under side of the slide with sufiicient force to hold it in place. In addition to this movement,-or in place of it,we may use the elastic tail piece I which, aL o. projects above the plane of the shoulders II and engages the under side of the slide. But we prefer to use both of these means for preveming the means for holding the slide against; random this prevents the finger from slipptrg o f as random movement of the slide, and do so in ractice.

\Vhat we claim as new and desire to secure by Letters Patent is:

1. he combination with the baseplate of a sewing machine, of a depressible device secured thereto adjacent to the shuttle race and having a portion projecting over the shuttle race am lying in a plane above the horizontal plane of the shuttle, said device being adapted when dc )rcssed to engage the point of the shuttle and thereby flip it out of the carrier, substantially as described.

.2. The combination with the baseplate of a sewing machine, said base-plate having a shuttle race and a cove at the front end of said race, into which the point of the shuttle projects when at the limit of its forward movement, of a deprcssible device secured to the base-plate and having a portion projectin" over said cove in position to engage the point of the shuttle when depressed, substantially as described.

3. The combination with the base-plate of a sewing machine, having a shuttle race, of a s ring secured to the basc-plate adjacent to tiie shuttle race and having a depressible portion projecting over the shuttle race in position to enga e the point of the shuttle, substantially as described.

4. The combination with the base-plate of a sewing machine, having a shuttle race, of a. spring secured to the base-plate adjacent to the shuttie race and having an enlarged head projecting over the shuttle race and adapted to engage the. mint of the shuttle, substantially as descri Jed.

5. The combination with the base-plate of a sewing machine. having a shuttle race and a slide for covering the said race, of a, spring secured to the base-plate beneath the slide and engaging the under side thereof for pre venting its random movement, said spring having .a depressible portion projectin over the shuttle race in a plane above the sauttle and in position to engage the point of the shuttle, substantially as described.

6. The combination with the base-plate of a sewing machine, having a shuttle race and having a cove at the forward end of said race, of a flipper secured to the base-plate adjacent to said cove, said flipper having a portion perforated for the passage of the retaining screw and a spring portion projecting rearward therefrom and over the cove in position to engage the point of the shuttle when depressed, substantially as described.
